230977 – Lube Zerk Fittings – 2.000″ Style – #10-32 Thread Size – 0.344″ Overall Length

Greaseable driveshaft components depend on zerk fittings remaining functional. A clogged or broken zerk is the most common cause of premature U-joint failure in greaseable applications -- the technician attempts to grease the joint at service but gets no grease in because the zerk is blocked, and the joint runs dry. The 230977 is the Spicer 2.000-inch style zerk with 10-32 thread and 0.344-inch overall length.

Replace zerk fittings at every major service if they show signs of damage or cannot be cleaned with a needle cleaner. A new zerk costs almost nothing -- a dried-out U-joint costs hours of labor. After installing the new zerk, apply grease immediately and verify the old grease purges from the bearing caps before considering the service complete.
